Danger (H280) Contains Gases (General P210) Keep away from heat/sparks/open under Pressure; may flames/hot surfaces. - No smoking. explode if heated. (Reaction P377 + P381) Leaking gas fire: Do not (H220) Extremely extinguish, unless leak can be stopped safely. Eliminate flammable gas. Dissolved Gas all ignition sources if safe to do so. (P410 + P403) Protect from sunlight. Store in a well ventilated place. 2(c) Describe any hazard not otherwise classified that have been identified during the classification process • Acetylene is a lighter than air gas. It may escape past closure seals that are air-tight and accumulated in inadequately vented storage spaces. • By-products generated in use, such as welding and flame cutting, may generate hazardous fumes and gases. • Large amount of potential energy resulting from compression of the gas makes the cylinder a potential rocket or fragmentation bomb. 2(d) Where an ingredient with unknown acute toxicity is used in a mixture at a concentration = 1% and the mixture is not classified based on testing of the mixture as a whole, a statement that X% of the mixture consist of ingredient(s) of unknown acute toxicity is required. Acetylene CAS No. 74-86-2 consists of 0% of unknown acute toxicity.
